bolding keyword is messing header

Hey guys

I get all the page output and check it wit preg_replace to bold some words . but it will bold a word if it finds it in my page html header code and that's messing up my page.


$string = get_ob_content();
$words_to_bold = array("word1","word2","word3","word4");
echo preg_replace('~('.implode('Ś', $words_to_bold).')~','<b>$0</b>',$string);}

How can i tell it to skip the content between the head tags?

Thanks

Can you split out everything before <body>, work on the remainder and then join it back together?

Going with what g1smd said, strpos [php.net] will be useful here finding the location of

<body>

and

</body>

and grabbing the content in between. Once you find the location you just need the substr [php.net].

One way would be to find a <body tag before allowing the preg_replace to bold any words. Use a boolean datatype like $bodyFound = false; ... Once it's set to TRUE, allow the regular expression to bold the keywords.

Sorry g1smd, not trying to hijack your idea. Didnt fully read the answers before posting. My apologies :)

I was guessing, and not sure if someone else might come up with a better method... so don't apologise, thanks for posting.

What about skipping all html tags?

how to tell it "only bold" content which are not in the html tags?
